Abnormal reflex

This code signifies a neurological finding where a patient exhibits reflexes that deviate from the normal physiological response. This can include hyperreflexia (exaggerated reflexes), hyporeflexia (diminished reflexes), or absent reflexes, indicating potential underlying neurological dysfunction. It represents an objective sign identified during a physical examination.

This code is appropriate when documentation explicitly states an abnormal reflex finding, such as "hyperactive patellar reflex," "diminished biceps reflex," or "absent ankle jerk." It is typically used as a symptom code when a definitive diagnosis for the underlying neurological condition has not yet been established. Supporting documentation includes neurological exam findings in physician notes.

• Do not use this code if a more specific diagnosis explaining the abnormal reflex is documented (e.g., stroke, spinal cord injury).
• This code should be sequenced as a secondary diagnosis when a primary condition is being treated, unless the abnormal reflex is the sole reason for the encounter.
• Ensure the medical record clearly specifies which reflex is abnormal and the nature of the abnormality (e.g., hyperactive, diminished, absent).
